I purchased from SJS Cycles in UK three pairs of the GB randonneur bars that several members expressed interest in. They arrived today - exquisitely engraved with the pattern shown on the CR site - the one with the map of Great Britain. 43cm wide center to center. They are 1" (25.4cm) at the stem clamp. They are randonneur bend, i.e. rather than flat tops, the bar bends slightly upward on either side of the clamp. £17 (about $25) but freight from UK will add to that. SJS also have nice British-made stems with 1" clamp in 5, 8 and (I think) 11cm. The site says these are GB, but I can't find GB markings, though they are clearly marked as British made. These are similar to the TTT Record stem.
